R. H. HILL INSTRUMENT TRAY Sept. 8, 1931.

l, 1929 2 Sheets-Sheet 2 Inventor Jial/ZE'ZZ --By @M Patented Sept. 8, 1931 UNITED STATES REMMEL H. HILL, OF COLUMBIA, MISSOURI INSTRUMENT TRAY Application filed Novemmr This invention relates to a structure which is characterized especially by an improved tool tray principally designed to accommodate dental instruments, implements and the like.

In carrying the invention into effect, I have evolved and produced a novel combination consisting of a cabinet door and a removable tray therein, said tray being especially constructed to occupy an inclined position in of parts.

Figure 3 is a longitudinal fragmentary section on the line 3 3 of Figure 1.

Figure i is a top plan view of a slightly different species of tray.

Figure 5 is a view like Figure 2 showing the last named tray in the cabinet drawer.

Figure 6 is a sectional view of the line 6-6 of Figure 4.

In Figure 2, the reference character 7 designates an ordinary cabinet drawer and 8 represents one of theI forms of trays. This tray is arranged removably within the drawer in a diagonal inclined position. The tray is of the construction seen in Figure 1, being of general rectangular configuration and including a suitably shaped bottom 9, a pair of end walls 10, front wall 11, and a backwall 12.

The front wall as well as the end walls are at right angles to the body. The back wall 12 is at a substantially obtuse angle with respect thereto in order that it may engage the adjacent side wall of the drawer as seen in Figure 2. In this way, the entire tray is held in an inclined position, so that by 1, 1929. Serial No. 404,038.

pulling the drawer out the dentist can readily see the various instruments arranged therein.

In order to enable the instruments to be placed in an orderly fashion in the drawer, I provide a retainer which is generally designated by the reference character 13.V This is in the nature of a false bottom and in fact consists of a strip of metal which is bent upon itself into corrugated formation to provide a multiplicity of transversely disposed open ended pockets 14 for reception `of the various tools 15. Y

This separates the tools and facilitates selection as well as expeditious and systemmatic replacement. Thus, the holder constitutes somewhat of a *falseV bottom and is constructed with a multiplicity of pockets. Itis approximately one-half of the width of the complete tray.

The tray 16 represented in Figure 4 is practically identical with the exception that it includes additional parts; namely, a pair of upstanding longitudinally spaced flanges 17 and 18 whose upper edges are formed with longitudinally spaced notches 19 providing a keeper seat for the instruments 2O which may be conveniently suspended therein.

I wish to call attention to the following advantages derived by using trays in combination with cabinet drawers of the type shown. For instance, my forceps, eXolever, and elevator trays have a structure different from any `surgical trays known to me. They are so constructed as to snugly fit withinthe drawer of a dental cabinet in a slanting position asshown in the drawings.

The two trays are provided to lill a specific need and a specific purpose; namely, they are individual receptacles for two particular types of instruments, for example, dental forceps, exolevers, and elevators. These Vparticular forms of instruments are too large and cumbersome to be placed in small instrument trays as are generally provided in the trade.

It is understood that these traysare intended for dental office cabinets and hospitals, and not for surgical bags.

It is understood that the trays remain 1n the drawers of the cabinet while the instruslippage, especially when the completetray isl arranged in the drawer. The notched flanges keep the elevators in such a. position that the cutting and working parts are elevated above the bottom and maintained away from each other to prevent Chilling. Then. too, a structure of' this type is regarded ascharacteristic and individual in nature as well as susceptible opromoting sanitary conditions.

Itis thought that by carefully considering the description in connection with the drawings a, clear understanding of the invention will be had.f Therefore, a more lengthy desoription is regarded as unnecessary. Minor changes` i-n shape, size,y materials and rearrangement of elements coming within the field of invention claimed may be resortedl to in actual practice ifl desired. v-

I claimn:Y

l.. In a structure ofthe class described, in combination, a drawer, a relatively shallow tray' arranged in dl draiwer and compris-f ing a bottom, end walls, ay frontf wall, and a rear wall, said rear wall being disposed at an approximate, obtuse angle with. respect to the bottomI and being intended to bear against.

the inner fsurface of the back wall of the drawer in order to hold the tray in a forwardly and downwardly inclined position, and means.

in saiid' tray for retaining said instruments separated and readily accessible and removable.

2*. As a new product of manufactine, a dent-al tray, a false bottom therein, said false betteln` being in the nature of a` sheet of metal bcntinto corrugati ons forming a multiplicity of individual open ended instrument receiving' pockets., and a pair of spaced parallel' longitudinally upstand in g, flanges `in the tray provided along their upper edges with longitudinally spaced notches constituting keepers fory removable reception of individual instruments. n

3. As a nen1 product of manufacture, a den-taltray, ai false bottom therein, said false bottomy being a sheet of metal bent at longin tndinallyspaced points into corrugations formi-nig a. multiplicity of individual instruf ment receiving pockets, and. a pair of spaced parallellongitudinally upstanding flanges iny the tray provided along their upper edges with longitudinally spaced notches constituting keepers for removable reception of indiiividuafl instruments, said notches being of a height lessithan the walls ofthe tray and the notches being spaced above the bottom of the tray to hold the pointed end of certain oi the instruments in spaced relation from the bottom to prevent Contact and chilling.

In testimony whereof I affix my signature. ..0
